利用直流/直流开关稳压器实现低噪声和低 EMI 性能
降低开关稳压器的 EMI 和噪声对工程师来说是一项挑战。由于 PCB 布局太混乱，系统可能不符合 CISPR 标准。因此，许多电源设计人员干脆转而使用线性稳压器，以此来避免令人头疼的减少发射问题。但由于效率较差，线性稳压器会出现潜在的散热问题，而这些问题可以通过使用开关稳压器来避免。如何做到两全其美？此培训系列和文档旨在说明工程师如何获得开关的出色效率，同时克服 EMI 和噪声难题。文中提供了 EMI 和噪声最佳实践的概念和实际示例，并提供了有关为汽车系统和噪声敏感型模拟电路供电的具体评论。熟悉用于监管传导和辐射 EMI 的各种标准可能会有所帮助。
